I, JAKOB E; Nonsenf United States, residing I ounty of Schenectady, rk,fhave invented certain iil rovements in Arina r l achines-, of which the pecification.

and its object is to provide geinent of thearmature conrings 'at the opposite ends of the armature may be separated without disconnecting the armature conductors from the collector rings.

My invention'consists in forming the armature conductors in separable parts so that the two sets'of collector rings may be drawn apart" without disturbing the connections" the conductor may be made continuous greatly-facilitating its proper insulation. I x invention will best be understood by referenceto the accompanying drawings, in which Figure 1 shows a side elevation, partly in cross-section, of an armature for a unipolar invention; and Fig. 2 shows an enlarged .c In the drawings, A represents the armature core, which is divided at its center into The particular construction 0t core shown forms no part of my present invention, but 18 t-hecontion, Serial No. 27 9,624, September 1-..4, 1905 A set of collector-rings B is carried at each end of the armature, and the two sets are movable away from each other either by moving either set on the core or by separatcomposed.

be seen that the halves of the armature core may be pulled apart or either set of collectorrings removed'without disconnecting the armature conductors from the collectorrings.'- I v I have found that the conductor'construction shown inthe drawings gives asu thciently 'good electrical connection betjween the two parts of the conductor, because of the contact pressure between-them, pro-' duced by centrifugal-force." Therefore no special means for binding the meeting'ends of the conductor parts together is necessary, The omt'may accordingly be made "inside" the armature core as shown, and since the conductor is of uniform diameter through the core a continuous sleeve of insulation, .1),

may be employed as shown, most eliectively insulating the conductor.

What- I claim as new, and desire-to'secure by Letters Patent of the United States, -is,-v Y 1. An armature for unipolar machines having two setsof collector rings, and armature conductors between said sets of rings and connected thereto, each conductor being divided at a point between said sets of rings 2. An ariiiature for unipolar machines having two sets of'collector rlngs, and armature conductors between said sets of rings and connected thereto, each conductor being divided at a point near its center into separable parts.

In an armature for unipolar machines, armature coiuluctors divided, near their centers into separable parts, one of said parts being adapted to enter the other at their meeting ends.

l. In an armature for unipolar machines, collector-rings at opposite ends of the armature, armature conductorsdivided at a point between the two sets of rings into separable parts, each of said parts being secured near its outer end to one of said collector-1irigs} 5. In an armature for unipolar machines,

;c'ol lector-rings at opposite'ends of the arma- Pure, armature conductors divided at a point betweenthe two sets ot rings into separable L ELEO TRIO ice parts, each of said parts being secured near its outer end to one of said. collector-rings,

and the inner end of one of said parts being adapted to enter the inner end of the other part.- Y i 6. An armature for umpolar machines, comprising a core, sets ot collector-rings at opposite ends of the core, said sets being movable away from each other, and armature conductors" each formed of separable partss cured respectively to collector-rings at opposite ends of the core.v

7. An armature for unipolar machines, comprising a core, two sets of collector-rings at 0 posite ends of the core,'j-and armature con uctors connected at both-ends to collector-rings, both core and conductors being separable between the sets into two parts. t 8. An armature for unipolar machines, comprising a core, two sets of collector-rings 1;, at op 'osite ends of the core, said sets being mova 1e away from each other, and armature conductors connected at bothends to collector-rings and separable between the sets of collector rings into-two parts, the innr end of one of the conductor parts being adapted to enter the inner end of the other part of the conductor. I,

9. An armature for unipolar machines,

of collector irings comprising, & GQ T dlvided into separable vnore into separableparts, and a continuous sleeve of Insulation-surrounding the conductor and extending through the core. I

10. An armature for unipolar machines, comprising a core divided into separable parts ,armature conductors extending through the coreand divided within the body of the core into separable parts, the inner end of one of the conductor parts being. adapted to enter the inner end of the other part of the conductor, and a continuous sleeve of insulation surrounding the conductor and extending through the core.

In witness whereof, I have hereunto set 40 my hand this 23rd day of April, 1907.
